In a forest, the nitrates contained in the nucleic acids of a bear can be made available again to primary producers after the bear dies, through the action of: A Vultures that eat fat and muscle from the carcass B Bacteria that decompose organic molecules back to their inorganic components C The toxic mushroom that the bear ate, which killed it D The salmon that are an important food source for the bear

Option B

Explanation:

In any food cycle or ecosystem, the top most organisms are the decomposers. They are kept above the tertiary species because when the tertiary species die, these decomposers or micro-organisms feed on them and convert organic material with in them into reusable form/nutrients/chemicals.  

These nutrients get mixed with the soil and are reused by the plants and trees (producers) for making food for all other organism in the food chain by entrapping solar energy.  

Hence, option B is correct

this is a good question! i'll do some research and come back when i have the answer!

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
